Cloud security architecture is the blueprint for protecting identities, workloads, data, networks, and control planes across cloud environments. It encompasses policies, trust boundaries, telemetry, and enforcement paths that govern cloud computing security under the shared responsibility model.
Architecture becomes useful when a team can follow a privileged request through its enforcement points or trace a failed control to the affected asset, accountable owner, and remediation evidence. These two paths provide a practical way to evaluate whether the deployed environment matches the intended design.
This guide draws on AWS, Microsoft, Google Cloud, IBM, CISA, NIST, and Cloud Security Alliance guidance, alongside Cloudaware product documentation reviewed in October 2026. The hybrid payments scenario later in the article is illustrative.
Architecture establishes where security controls belong and how they interact. CSPM evaluates deployed configurations against selected policies, while cloud monitoring tools provide telemetry about workload behavior and dependencies. Both help teams verify whether their architecture is operating as intended.
Key insights
The following principles can serve as review criteria for a deployed cloud environment.
- Cloud security architecture defines the operating model. It establishes trust boundaries, enforcement points, responsibilities, and evidence requirements across the shared responsibility model
- A diagram must show how controls work. Trace a privileged request from identity to the protected resource, then trace a failed control from detection to accountable remediation
- Multi-cloud design requires control translation. AWS Organizations, Azure management groups, Google Cloud resource hierarchy, and IBM resource groups provide different governance structures. Architects must identify where each provider enforces policies and records violations
- Frameworks and reference architectures serve different purposes. NIST CSF 2.0 describes cybersecurity outcomes, CSA CCM defines cloud security controls, and reference architectures illustrate implementation patterns
- Security findings need operational context. An affected asset, business service, current owner, exception state, and verification record determine whether a detected problem can be managed through to closure
For architecture review preparation, see our guide on conducting a cloud security architecture review.
How to read a cloud security architecture diagram
A cloud security architecture diagram should show how identities interact with workloads and data, where controls enforce access decisions, and how security events reach the teams responsible for remediation.
A diagram that identifies services without showing these relationships may be useful for inventory, but it provides limited evidence of the security design.
Cloud security reference architecture showing how access decisions are enforced and control failures are traced to accountable owners and verified resolution.
Check five paths when reviewing the diagram:
- Trust boundaries: Identify organization, account, subscription, project, cluster, network, and on-premises boundaries, including connections between them
- Identity paths: Show where human users, workloads, pipelines, vendors, and emergency accounts authenticate, receive authorization, and cross privilege boundaries
- Data paths: Locate sensitive data stores, encryption keys, replicated data, and transfers between security domains
- Control points: Place IAM policies, network enforcement, runtime detection, and configuration checks at the points where they actually operate
- Evidence paths: Connect access decisions and failed controls to audit records, findings, responsible teams, exception records, tickets, and verification results
Review the diagram in two passes.
1. First, trace a privileged request. Identify the principal, authentication source, role or permission boundary, enforcement point, destination workload, and audit record. The purpose is to confirm where access is allowed or denied and whether that decision can be reconstructed.
2. Next, select a failed security control. Follow the event from detection to the affected asset, owner, remediation record, and verification step. Check whether the responsible team can demonstrate what changed and when the control was evaluated again.
An architecture review is incomplete when a control has no clear enforcement point, a finding has no accountable owner, or a remediation claim cannot be verified.
The same review method applies whether the environment contains one AWS account or hundreds of accounts, subscriptions, and projects across multiple providers.
4 core components of cloud security architecture
Cloud security architecture consists of four interdependent components: identity and access management, network security, data protection, and workload security.
Each component controls a different part of the attack surface. Their effectiveness also depends on how permissions, network paths, data classifications, and workload configurations interact.
The core components are:
- Identity and access management
- Network security and micro-segmentation
- Data protection and encryption layers
- Workload protection and runtime security
Identity and Access Management (IAM) as the foundation
Identity and access management determines which human and machine identities can access cloud resources, what actions they can perform, and under which conditions those permissions remain valid.
A modern cloud estate depends on several types of identity. Employees authenticate through SSO, workloads assume roles, pipelines call APIs, and third-party systems use service identities. Each access path creates a potential privilege boundary.
The main architectural decisions include:
- Privileged authentication: MFA should protect administrative access, production changes, break-glass accounts, and other high-trust paths
- Role-based access control: Permissions should reflect actual responsibilities, such as allowing a platform engineer to manage clusters without granting access to unrelated finance data
- Identity federation: Access across cloud providers, SaaS applications, and on-premises systems needs a consistent authentication and lifecycle model
Least privilege becomes difficult to maintain when teams create roles for immediate requirements but never remove permissions after those requirements change.
For example, a deployment pipeline may need temporary access to update a production service. If its role also permits reading unrelated storage buckets or modifying account-wide policies, the privilege boundary extends beyond the deployment task.
An identity-first cloud architecture should account for the authenticated principal, session context, device posture where relevant, privilege scope, and conditions under which access must be revoked.
Network security and micro-segmentation
Cloud security network architecture determines which systems can communicate and how network controls restrict unwanted access or lateral movement.
The design starts with the communication paths a workload needs. A public API may require inbound HTTPS traffic, while the database behind it should accept connections only from approved application components.
Common controls include:
- Virtual networks and VPCs for network-level separation
- Security groups and equivalent cloud firewalls for workload traffic restrictions
- Network ACLs for additional subnet-level filtering where supported
- Private connectivity, VPNs, and SD-WAN for approved hybrid communication paths
Network segmentation becomes more important after an initial compromise.
Consider a compromised build runner in a shared development environment. If routing and firewall policies allow it to reach production databases, the attacker gains additional opportunities even without obtaining a new cloud identity.
Micro-segmentation reduces these reachable paths by restricting communication between workloads according to their function and trust requirements.
For hybrid infrastructure, the review must extend across private connections and cloud-native network controls. A VPN or dedicated connection establishes transport, but does not demonstrate that the same access restrictions apply at both ends.
Review allowed traffic against actual service dependencies and investigate paths that remain open without a current operational requirement.
Data protection and encryption layers
Data protection architecture establishes how sensitive information is classified, encrypted, accessed, transferred, and retained throughout its lifecycle.
The control design should cover:
- Encryption at rest for persistent storage
- Encryption in transit between clients and services
- Confidential computing or encryption-in-use mechanisms where the processing scenario requires them
- Key management and separation of duties
- Data classification and DLP policies
- Retention, masking, and access monitoring
Two decisions deserve particular attention.
1. Key ownership
Provider-managed encryption keys can simplify operations. Customer-managed keys give organizations more direct control over key policies, access permissions, and lifecycle decisions. The appropriate model depends on data sensitivity, regulatory obligations, and operational requirements.
2. Data classification
Encryption alone does not establish whether a workload should access particular information. Customer records, payment data, application secrets, and public content require different handling rules.
Without a classification model, teams may enable encryption broadly while leaving data transfers, service permissions, and retention policies inconsistent.
GDPR, HIPAA, and SOC 2 can influence the required controls and evidence, depending on the organization's scope and obligations.
A design review should establish which identities can decrypt sensitive information, which services process it, where copies are created, and how unauthorized access is detected.
Workload protection and runtime security
Workload security protects virtual machines, containers, serverless functions, and their supporting configurations after deployment.
Infrastructure-as-code can define a secure baseline, but the runtime environment can diverge from that baseline. A container may receive a vulnerable dependency, a function may inherit excessive permissions, or an administrator may change a VM configuration outside the approved deployment process.
Workload protection commonly includes:
- Cloud workload protection platforms (CWPP)
- Container image scanning and runtime security
- Serverless permission and dependency checks
- VM hardening and configuration baselines
- Runtime detection and configuration drift monitoring
- Asset context linking workloads to owners and business services
Different workload types require different controls. VM security depends partly on operating system configuration and patching. Containers introduce image provenance and runtime isolation considerations. Serverless services require attention to execution roles, event sources, and integrated services.
A runtime finding is more actionable when the security team can identify the affected workload, deployment environment, responsible application, and recent configuration changes.
For example, an exposed compute instance may support a customer authentication service. Its importance depends partly on its relationship to the service and the access paths available from that instance.
Runtime detection remains a separate control path. When Cloudaware NeoSec is configured on supported hosts, its host-based intrusion-detection workflow can surface security events in the Cloudaware environment and associate them with monitored assets.
Coverage depends on deployed agents, enabled detection rules, and integration configuration.

Cloud security architecture across major providers
AWS, Azure, Google Cloud, and IBM Cloud support similar security objectives, but use different resource hierarchies and policy enforcement mechanisms.
The differences matter when architects design preventive controls, aggregate security telemetry, and assign responsibility across multiple environments.
Use the following table to locate equivalent architectural decisions rather than assuming that services with similar names provide identical capabilities.
| Provider | Governance hierarchy | Identity and preventive controls | Detective and evidence layer | Primary source |
|---|---|---|---|---|
| AWS | Organizations, organizational units, accounts | IAM roles, IAM Identity Center, service control policies | CloudTrail, AWS Config, GuardDuty, Security Hub CSPM | AWS Security Reference Architecture |
| Azure | Management groups, subscriptions, resource groups | Microsoft Entra ID, Azure RBAC, Azure Policy | Azure activity and resource logs, Microsoft Defender for Cloud | Azure landing zones |
| Google Cloud | Organization, folders, projects | IAM, organization policies, VPC Service Controls | Cloud Audit Logs, Security Command Center | Security, privacy, and compliance pillar |
| IBM Cloud | Accounts, resource groups | IBM Cloud IAM, access groups, context-based restrictions | Activity Tracker Event Routing and configured security services | IBM Well-Architected: Security and Compliance |
A hierarchy determines where some controls can be inherited or assigned. It does not demonstrate that those controls cover every deployed workload.
Review scope, policy exceptions, collected telemetry, ownership data, and remediation records separately for each provider.
AWS cloud security architecture
The AWS Security Reference Architecture (AWS SRA) guides deploying and managing security services in a multi-account AWS environment.
AWS accounts establish resource and administrative boundaries. AWS Organizations provides centralized account governance, while service control policies constrain the permissions available within member accounts.
The SRA describes a recommended structure, including dedicated security and infrastructure accounts. Organizations should adapt that structure to their operating model and compliance requirements.
Source: AWS SRA architecture diagram
Multi-account environments introduce a recurring problem: security controls may be centrally configured, but individual findings still need to be associated with their workload account and responsible team.
Several AWS services support this design:
- AWS Organizations establishes the account management hierarchy
- Service control policies (SCPs) define permission guardrails for member accounts without granting permissions themselves
- Amazon GuardDuty analyzes supported data sources to identify potentially malicious or unauthorized activity
- AWS Security Hub CSPM consolidates posture findings against supported security standards and checks
- AWS Well-Architected Security Pillar provides design and operational guidance for securing AWS workloads
The AWS shared responsibility model distinguishes security of the cloud from security in the cloud. Customer responsibilities vary by service and include relevant identity policies, application configurations, data controls, and operating system security.
When reviewing an AWS finding, the architect needs to know which account and workload are affected, whether the resource belongs to production, and what policy or configuration introduced the risk.
Illustrative AWS findings triage view showing how GuardDuty or Security Hub findings can be examined alongside account ownership, environment, recent changes, and related assets when the corresponding data is connected.

Azure cloud security architecture
Azure cloud security architecture uses management groups, subscriptions, and resource groups to structure governance across enterprise environments.
Microsoft Entra ID provides identity services, while Azure RBAC and Azure Policy govern access and resource configurations through their respective scopes.
Microsoft's Azure landing zone guidance describes a scalable architecture that separates central platform services from workload environments.
Source: Microsoft Azure landing zone architecture diagram
The management hierarchy allows platform teams to assign selected governance policies centrally while application teams manage resources within approved subscriptions.
Microsoft also documents how Azure Policy can enable Defender for Cloud across subscriptions belonging to a management group, including subscriptions with different owners. This is useful in organizations where workload teams operate independently but must maintain a common security baseline.
Microsoft Defender for Cloud evaluates resources against supported policies and compliance requirements. Its recommendations help security teams investigate misconfigurations and other identified risks. Where the required capabilities are enabled, recommendations can be assessed with additional exposure and risk context.
For enterprise architects, the next question is whether a recommendation can be associated with the correct subscription, application owner, and remediation process.

Google Cloud security architecture
Google Cloud security architecture is organized around an organization resource, folders, and projects.
IAM policies can be inherited through this hierarchy, while organization policies constrain supported resource configurations. The structure allows security teams to establish controls at different scopes without maintaining every rule separately for each project.
Google's enterprise foundations blueprint illustrates this model through organization policies, folder structure, IAM groups, centralized logging, and detective controls.
Two additional services address distinct security requirements.
VPC Service Controls help establish service perimeters that reduce data exfiltration risks involving supported Google Cloud services. Cloud Armor protects supported internet-facing applications through network and application-layer security policies.
The architect should verify where these controls apply rather than treating either service as universal coverage for all Google Cloud workloads.
When a finding involves a production project, the response depends on more than its severity. The security team needs to identify the affected resource, project owner, relevant data classification, and policy scope.
The Google Cloud Well-Architected Framework security pillar provides further guidance for these decisions.
IBM Cloud security architecture
IBM Cloud security architecture organizes resources through accounts and resource groups, with IAM policies controlling access to supported services and resources.
Access groups simplify permission assignment. IAM policies associate identities with roles and resource attributes, while context-based restrictions can impose additional conditions based on factors such as network location or endpoint type.
These mechanisms provide different layers of access control. A context-based restriction can limit where a permitted action originates, but does not itself grant the underlying permission.
For details, see the IBM Cloud IAM access concepts and context-based restrictions.
IBM also provides services relevant to auditability and key management. Activity Tracker Event Routing routes supported audit events to configured destinations. Hyper Protect Crypto Services supports HSM-backed key management for workloads with more demanding key custody requirements.
The IBM Well-Architected Framework: Security and Compliance places these decisions within a broader model covering application, data, identity, infrastructure, and detection controls. For a regulated workload, an architecture review should connect the affected resource group to its business service, access policies, audit events, and accountable owner.

Cloud security architecture frameworks and reference models
Cloud security frameworks and reference architectures address different parts of the design process.
A framework defines cybersecurity outcomes or control requirements. A reference architecture describes how systems, actors, and trust boundaries can be organized to meet those requirements. Training and design reviews help practitioners apply and validate the resulting decisions.
Selecting the resource according to its intended output prevents a control mapping from being mistaken for evidence of a deployed security architecture.
CSA reference architecture: Enterprise Architecture and Cloud Controls Matrix
The Cloud Security Alliance provides two complementary resources.
- The CSA Enterprise Architecture Reference Guide v2 describes a vendor-neutral methodology for relating business operations, IT operations, technology services, and security risk management. Architects can use it to identify reusable patterns, assess capabilities, and develop improvement roadmaps.
- The Cloud Controls Matrix (CCM) v4.1 is a cloud security control framework containing 197 control objectives organized into 17 domains. It supports control selection, assessment, and clarification of responsibilities across the cloud supply chain.
The practical distinction is the deliverable.
Use Enterprise Architecture when the team needs a common reference model for systems and responsibilities. Use CCM when the team needs to select security controls, define assessment scope, or map responsibilities to requirements.
Neither artifact independently proves that a control is operating in a deployed environment. That requires configuration evidence, testing results, and retained operational records.
CISA cloud security technical reference architecture
The CISA Cloud Security Technical Reference Architecture guides federal agencies adopting and securing cloud services.
Its coverage includes shared services, cloud migration, and cloud security capabilities. The reference helps federal programs structure decisions within formal authorization, oversight, and shared responsibility requirements.
Commercial organizations may also find the guidance useful when designing common security services across business units or dealing with complex migration dependencies.
However, federal assumptions do not automatically transfer to a commercial operating model. Teams should adapt relevant design principles to their own service boundaries, obligations, and approval processes.
Using the reference architecture does not establish that the organization's deployed controls are effective.
Choose the resource by the decision it needs to support
| Resource | What it provides | Use it for | Limitation |
|---|---|---|---|
| NIST CSF 2.0 | Cybersecurity outcome framework | Current and Target Profiles, governance, risk communication | Does not prescribe specific implementations |
| CSA Enterprise Architecture v2 | Vendor-neutral architecture methodology | Domains, relationships, capability planning | Requires adaptation to the current environment |
| CSA CCM v4.1 | Cloud security control framework | Control selection, mapping, assessment scope | Control mapping is not implementation evidence |
| CISA Cloud Security TRA | Federal technical reference architecture | Shared services, cloud migration, security governance | Federal assumptions may not fit commercial operations |
| SANS SEC549 | Cloud security architecture training | Threat modeling, IAM, network and data security design | Training does not constitute deployed-control assurance |
For example, a team preparing a cloud security architecture review could use NIST CSF 2.0 to define desired outcomes, CSA CCM to identify applicable controls, and a provider reference architecture to map implementation points.
Testing and operational evidence would then establish whether the controls operate as expected.
NIST SP 500-299 should not be treated as a current security reference. NIST discontinued further development of the draft in May 2018.
Security architecture for hybrid cloud environments
Hybrid cloud security architecture requires controls to remain effective when identities, traffic, workloads, and telemetry cross on-premises and cloud boundaries.
The full reference model is covered in our dedicated guide to hybrid cloud security architecture. Here, the focus is on the boundaries that affect the primary cloud design.
Consider an employee authenticated through an on-premises identity system who accesses a cloud workload through private connectivity.
The request may cross different policy scopes, logging systems, and infrastructure owners before reaching the destination. Each handoff creates a point where intended security controls and deployed configurations can diverge.
Typical review areas include:
- Identity federation and account lifecycle consistency
- Policy enforcement across cloud and on-premises systems
- Network transport and routing restrictions
- Security telemetry across both environments
- Ownership and exception handling at shared boundaries

How to apply security controls across on-prem and cloud
Existing data center controls such as firewalls, IDS/IPS, and SIEM remain relevant in hybrid environments. Their policies and telemetry must be coordinated with cloud-native controls.
A site-to-site VPN, AWS Direct Connect, or Azure ExpressRoute provides a connectivity mechanism, subject to its configuration. It does not establish consistent access restrictions across the connected environments.
For example, an on-premises firewall may block access to a sensitive service while a cloud-side security group permits a broader route. The connection is operational, but the intended network restriction is inconsistent.
A hybrid review should establish:
- Whether on-premises firewall rules and cloud network controls enforce the intended communication policy
- Whether security monitoring covers relevant activity on both sides of the boundary
- Whether events can be correlated during investigation
- Whether policy exceptions have a named owner and review process
A control failure should be traceable to the boundary where it occurred, the affected asset, the responsible team, and the applicable policy.
Illustrative hybrid handoff view connecting failed controls to affected assets, owners, recent changes, and policy requirements.
This context helps distinguish a network configuration problem from a legitimate exception or an issue requiring changes in both environments.
Device-to-cloud security architecture patterns
Device-to-cloud architecture introduces additional trust boundaries between edge devices, gateways, networks, and cloud services.
An industrial sensor, camera, or controller must authenticate before connecting, communicate through approved paths, and retain the appropriate security configuration after updates or certificate rotation.
A compromised gateway or poorly managed device identity can create an unintended access path into cloud-connected services.
Where device identity meets cloud policy
1. Start with device identity
Each managed device should have an identity that can be validated and revoked.
Enrollment, credential rotation, and decommissioning processes must prevent retired or unauthorized devices from retaining access.
2. Restrict the communication path
Gateways, brokers, ingestion layers, and scoped APIs can limit which cloud services a device can access.
These controls should be selected according to the device type and expected communication pattern.
3. Review remote access
SSE, SASE, and Zero Trust Network Access may be relevant where remote administrators, vendors, or users need access to distributed environments.
The appropriate design depends on whether access is initiated by users, applications, or devices.
In every case, the architecture must define how trust is established, maintained, and revoked.
How to design a cloud security architecture step by step
Cloud security architecture design should begin with a business service and the trust paths required to operate it.
Starting with a service boundary helps architects connect security controls to concrete workloads, identities, data flows, and responsible teams before selecting or configuring enforcement technologies.
The practical sequence is:
- Select a business-critical service
- Define its boundaries and dependencies
- Review identities and privileged access
- Model threats and abuse paths
- Establish preventive controls at appropriate governance scopes
- Define telemetry, ownership, and exception handling
This approach adds investigation before implementation. The benefit is that each security control can be tied to an identified risk and a defined method of verification.
Before you draw anything, answer this
Which business service should the architecture protect first?
Choose a service with a meaningful operational or security impact, such as:
- Customer authentication
- Payment processing
- A regulated data pipeline
- A privileged administration service
The decision should reflect business criticality, sensitive data, external exposure, and dependencies.
This assessment also provides a starting point for a broader cloud security strategy.
Step 1: Draw the service boundary, not the cloud boundary
Start with one business service and identify the infrastructure and dependencies required to operate it.
Map:
- Users who access the service
- Supporting workloads
- Data stores and sensitive information
- Human and machine identities
- Internal teams and third parties with administrative access
The resulting boundary may span multiple accounts, subscriptions, projects, and on-premises systems.
This scope is more useful for threat modeling than a provider inventory alone because it identifies resources that can affect the same business process.
For a payment service, that might include an API gateway in AWS, an identity provider, a settlement database, and a reconciliation system maintained by another team.
Step 2: Put identity in the middle
Identity design determines which principals can act across the service boundary and how their privileges are restricted.
Review all authentication and authorization mechanisms involved in the service:
- On-premises Active Directory or Microsoft Entra ID
- AWS IAM roles
- Google Cloud service accounts
- Azure managed identities
- CI/CD credentials
- Third-party access
- Emergency administration accounts
For each privileged identity, establish where authentication occurs, which roles it can assume, and how access is revoked.
Federation alone does not resolve excessive permissions or inactive service accounts.
A vendor identity may authenticate correctly while retaining production access after a contract ends. A deployment role may accumulate permissions that are no longer required.
These conditions should be addressed through permission boundaries, lifecycle controls, access reviews, and monitoring appropriate to the identity type.
Step 3: Pressure-test the system before implementation
Threat modeling tests whether the proposed architecture limits realistic abuse paths.
STRIDE can help identify design-level threats such as spoofing, tampering, information disclosure, and elevation of privilege.
MITRE ATT&CK provides a knowledge base of adversary behaviors that can inform scenarios involving compromised identities, exposed workloads, and lateral movement.
Apply both to the selected service boundary.
Three useful review questions are:
- If a privileged identity is compromised, which systems can it reach?
- If an internet-facing workload is exploited, which services or data stores become accessible?
- If a configuration change bypasses the approved process, which control detects it?
Record the relevant trust boundary, preventive control, expected detection, and responsible team for each significant scenario.
This creates a basis for verifying the design after deployment.
Step 4: Set your hard rules high up
Controls that must apply consistently should be assigned at the highest appropriate governance scope supported by the provider and organizational model.
Examples include:
- Required security logging
- Encryption configurations
- Approved deployment regions
- Ownership and environment tagging
- Public exposure restrictions
- Restrictions on services used for sensitive workloads
Cloud security teams should distinguish controls that must remain centrally governed from decisions that workload teams can safely manage.
| Decision area | Centralize when | Delegate when |
|---|---|---|
| Identity baseline | Shared identities, regulated workloads, or multiple teams require consistent access controls | Workload teams can operate within centrally defined permission boundaries |
| Logging and telemetry | Cross-account or cross-cloud investigation requires common records and retention requirements | Teams need additional workload-specific telemetry |
| Network guardrails | Public exposure or lateral movement could affect multiple services | Application teams need to define approved service-to-service communication |
| Policy exceptions | Risk acceptance or regulatory oversight requires formal approval | Designated service owners can review exceptions within an approved governance process |
Local control should not bypass mandatory security requirements.
A centrally defined baseline can establish minimum controls while allowing teams to implement additional protections where their workloads require them. For further implementation guidance, see our cloud security best practices.
Step 5: Decide what must always stay visible
Security telemetry becomes useful when it supports investigation and control verification.
For a failed security check, the initial review should establish:
- What failed?
- Which asset is affected?
- Who owns the asset?
- Which environment or business service depends on it?
- What changed before the failure was detected?
Those answers may come from several systems: cloud configuration records, IAM logs, vulnerability scanners, deployment histories, and CMDB relationships.
An architecture review should identify which system supplies each record and whether the information can be correlated.
Cloudaware can help relate configured security findings to CMDB context, including asset ownership and available change history.
Illustrative asset change history showing the state changes a reviewer can examine when investigating a failed control.
What this looks like in practice: A hybrid payments service has a public API in AWS, customer identity federated through Microsoft Entra ID, an Azure analytics pipeline, a settlement data store in Google Cloud, and a legacy reconciliation system on-premises.
The architecture team would:
- Define the payment service boundary across all relevant environments
- Identify human and machine identities with administrative, deployment, and data access
- Map transaction and settlement data flows between systems
- Model compromised identity and workload scenarios
- Identify governance controls that must apply at provider or organizational scopes
- Confirm that critical assets have accountable owners and relevant audit records
This process may reveal an AWS workload role with unnecessarily broad access, an integration identity without an effective credential lifecycle, or inconsistent restrictions on settlement data.
The purpose of the review is to identify those conditions while their enforcement and ownership can still be corrected through the architecture design.
Step 6: Design the exception path before the first exception arrives
Cloud security architectures need a defined process for legitimate deviations from standard controls.
A legacy integration may require an unsupported configuration, or a vendor may need temporary access that does not fit the normal policy.
Those exceptions should be documented and reviewed rather than left as permanent, untracked configuration differences.
An exception record should contain:
- Accountable owner and named approver
- Approval timestamp and affected assets
- Reason for the exception and accepted risk
- Compensating control
- Expiry date or review cadence
- Monitoring and evidence requirements
- Criteria for closure
At review time, confirm that the owner remains accountable, the affected assets are still within scope, the compensating control is operating, and the approval has not expired.
An exception without current ownership or review evidence creates a governance gap, even when the underlying technical configuration remains unchanged.

Turn the architecture into something your team can actually run
A deployed security architecture needs a reliable way to connect control failures to affected assets, business services, accountable owners, and remediation evidence.
Cloud provider consoles and security scanners supply important signals. However, those records may not contain the application relationships and organizational context required to route every issue to the responsible team.
For configured sources, Cloudaware CMDB relates cloud and on-premises configuration items to applications, environments, owners, and available change history. Cloudaware compliance capabilities can evaluate configured controls against CMDB data and generate findings that support review and remediation workflows.
A cloud security architect can use this context to:
- Scope controls using supported CMDB fields, such as application, account, environment, or tags
- Distinguish failed checks from approved exceptions and out-of-scope resources
- Route findings through configured Jira or ServiceNow workflows
- Review available policy evaluation records, status changes, and remediation history
- Compare compliance coverage across relevant services, environments, or teams
For example, a storage policy failure in a production account can be reviewed together with the affected asset's application and owner information.
The remediation team can then determine whether the failure requires a configuration change, an approved exception, or additional investigation.
Cloudaware provides CMDB context and configured workflows around supported data sources. It does not replace the provider's native security controls or the underlying scanner. Coverage depends on connected integrations, maintained ownership data, policy settings, permissions, and data refresh timing.
For a practical evaluation, bring one control to a Cloudaware specialist: the policy, affected asset, source of ownership data, exception requirements, ticket destination, and evidence needed for closure.
